Tephra Impact Lab - Taupo Volcano
06 Dec 2011 | Contributor(s): Tom Wilson, Leah Michelle Courtland
This lab requires students to produce a pre-eruption tephra risk assessment for Taupo volcano, using Tephra2. It requires students to consider the eruptive history of Taupo volcano and a volcanic unrest scenario is provided, so that students must decide what magnitude and style of eruption is...

Tephra inversion with Tephra2 and the Metropolis-Hastings algorithm
21 Jun 2020 | Contributor(s): Qingyuan Yang, E Bruce Pitman, Marcus I Bursik, Susanna Jenkins
We couple the Metropolis-Hastings algorithm (Hastings, 1970) with the volcanic ash transport model Tephra2 (Bonadonna et al, 2005; 2010), and present the coupled algorithm as a new method to estimate the Eruption Source Parameters (ESPs) of volcanic eruptions based on mass per unit area...

Tephra isopach, extent and volume calculation in R
04 Mar 2016 | Contributor(s): Qingyuan Yang, Marcus I Bursik
The method presented here is used to interpolate the thickness distribution of tephra fall deposits from point measurements. It first reconstructs the general thickness decay pattern, or "trend," and then models the residuals that cannot be explained by the trend with...
